BRUSH FOR COTTON GINS Filed Aug. 13, 1929 INVENTORS. mflimalbrbefi'Patented July 1, 1930 stars Afar WILLIAM C. TORBETT, OF WAQO, TEXASBRUSH non common GliNS Application filed August 13, 1929. SerialNo.285,551.

This invention relates to a cotton gin brush for use in connection withcotton gin stands. I

AS is well known, all cotton gin-stands from as to 60 inches, dependingon the size of the gin stand; this brush is of a cylindrical shape. Thebrush cylinder has inset insert portions having wooden bars 19 arrangedtherein. Each'bar carries a row of bristles. These bars are set atintervals around the cylinder and during the operation of the gin stand,the britsles act to sweep the cotton against the saws that [L5 separatethe lint from the seed. In wet or damp weather the brush cylinders swelland are shifted out of balance and further the bristles lose theirstiffness, the result being that when damp or wet cotton is run into thegin stand it will adhere to the bristles, gomingl such action beingtermed in this line of manufacture.

The object of a cotton gin brush, in accordance with this invention, isto overcome the disadvantages referred to and to this end the inventionaims to provide in a manner as hereinafter set forth a gin brush con'structed of sheet metal and carried by a metallic or wooden head or drumand with the brush set up in a manner to include fans or protrusions asa substitute for the bristles for the purpose of sweeping the cottonagainst the saws.

A further object of the invention is to provide, in a manner ashereinafter set forth, a metallic cotton gin brush which is not affectedby temperature or moisture and free of any attack by rodents, as is thecase in brushes now generally employed as the rodents frequently destroythe bristles and oftentimes the sticks, which places the brush entirelyout of balance.

Further objects of the invention are to provide, in a manner ashereinafter set forth, a metallic cotton gin brush which is simple inits construction and arrangement, strong, durable, compact, thoroughlyefficient in its use, conveniently assembled and comparativelyinexpensive to manufacture.

' With the foregoing and other objects in are equipped with a brushranging'in length view the invention consists of the novel construction,combination and arrangement of parts as hereinafter more specificallydescribed, and illustrated in the accompanying drawings, wherein isshown an embodiment of the invention, but it is to be understood thatchanges, variations and modifications can be resorted to which fallwithin the scope of the claims hereunto appended;

In the drawings wherein like reference characters denote correspondingparts throughout the several views t Figure tie a perspective view of acotton gin brush in accordance with this invention.

Figure 2 is an end View thereof.

Figure 3 is an end View of a modified form.

The body of the brush, which is of tubular, cylindrical form, can be setup from a single length of sheet metal to provide a hollow cylinder asshown in Figures 1 and 2, or set up from a series of arcuate sections ofsheet metal as illustrated in Figure 3. 1

The brush includes a carrier 1 of circular cross section provided ateach end with a spindle2. The spindles 2 may be formed from a singleshaft which extends axially of the carrier 1 and projects from the endsthereof. The carrier 1 can be formed of any suitable material preferablywoodif desired. It is to be understood that the carrier can beconstructed in any desirable manner and of any desirable material.

Referring to Figures 1 and 2 the body of the brush is indicated at 3 andis formed from a length of sheet metal, bent in cylindrical form withthe lengthwise edges thereof in abutting relation and secured togetherin any suitable manner.

The body portion 3 is provided with outwardly bent folds to formlengthwise extending, spaced, radially disposed blades, wings, vanes,fans or protuberances 4 of tapered cross section. The blades, wings,vanes, fans or protuberances will be hereinafter termed vanes and areemployed for the same purposes as the bristles, that is to say forsweeping the cotton against the saws which separate the lint from theseed.

The vanes correspond in length to the length of the body portion and areformed from inherent parts of the metallic sheet from which the bodyportion 3 is set up.

Referrin to Figure 3, which illustrates the modifie form of brush, thehollow body portion generally indicated at 5, is of circular crosssection and formed from a series of abutting sections 6, of arcuate formin cross section and with each section 6 formed from sheet metal andprovided with a plurality of radially disposed vanes 7 of tapered crosssection. Preferably each section 6 will be provided with outwardly bentfolds to form a pair of spaced vanes. The abutting edges of the sections6 are to be secured together in any suitable manner.

The body portion 3 or the bod ortion 5 snugly engages the periphery o te carrier 1 and suitably connected therewith, whereby the carrier andbody portion will bodily rotate in unison. Further the body portion ofthe brush is so secured to the carrier to prevent its shiftingcircumterentially with res ect to the carrier.

In bot forms shown the radially disposed vanes are equall spaced withrespect to each other on the b0 y portion. The vanes 7 are formed ofinherent parts of the sheet metal from which the sections 6 are set up.

The vanes are so set up whereby they are formed of two parts, that is tosay a leading part and a follower part and with said parts spaced fromeach other thereby providing for the vanes to have a slight resilientcharacteristic. The outer ends of the vanes are sharp and uninterruptedfrom end to end.

It is thought that the many advantages of a metallic cotton gin brush,in accordance with this invention, can be readily understood, andalthough the preferred embodiment thereof is as illustrated anddescribed, yet it is to be understood that changes in the details ofconstruction can be had which will fall within the scope of theinvention as claimed.

What I claim is:

1. A cotton gin brush comprising a onepiece body ofsheet metal consistinof a ollow, cylindrical metallic body portion for snugly enveloping arotatable carrier therefor, and said body ortion bein formed 7 withoutwardly bent olds to provide a plurality of outwardly directed,radially disosed metallic vanes extending from said ody ortion, saidvanes in cross section bein o tapered contour and spaced from each 0t orat their inner ends.

2. A cotton gin brush comprising a onepiece body of sheet metalconsisting of a ollow, cylindrical metallic body portion for snuglyenvelo ing a rotatable carrier therefor and sai body ortion bein formedwith outwardly bent olds to provide a plurality of outwardly directed,radially disposed metallic vanes, said vanes in cross section being oftapered contour and equally spaced from each other at their inner ends.

3. A cotton gin brush comprising a hollow, cylindrical metallic bodyportion for snugly enveloping a rotatable carrier therefor, and saidbody )ortion being formed with outwardly bent olds to provide aplurality of outwardly direct-ed, radially disposed metallic vanesprojecting from and merging at their inner ends in said body portions,said vanes in cross section bein of tapered contour and spaced from eaciother at their inner ends.

4. A cotton gin brush comprising a hollow, cylindrical metallic bodyportion for encom assing a carrier therefor and provided wit outwardlybent folds to form a plurality of spaced, outwardly directed, iiitegral,radially disposed metallic vanes, each of said vanes in cross sectionbeing ta ered and formed of a leading part and a fol ower part s acedfrom each other and further forum with an uninterrupted outer edge, saidvanes at their inner ends being spaced from each other.

5. A cotton gin brush comprising a hollow, cylindrical metallic bodyportion for encompassing a carrier therefor and provided with outwardlybent folds to form a plurality of spaced, outwardly directed, in tegral,radially disposed metallic vanes, each of said vanes in cross sectionbeing tapered and formed of a leading part and a follower part spacedfrom each other and further formed with an uninterrupted outer edge,said vanes at their inner ends being spaced from each other, the spacebetween said parts gradually increasing in width from the outer to theinner ends of the vanes and 1 opening into said body portion.

In testimony whereof, I afiix my signature hereto.

WILLIAM C. TORBETT.
